Do Smart TVs Stay Connected to WiFi?

Many people wonder if their smart TVs are still connected to WiFi when they are turned off. This question is crucial for both privacy and energy consumption concerns. Let's delve into the details of how and when smart TVs are connected to WiFi.

Understanding WiFi Connections in Off States

When a device is turned off, its WiFi connection is not entirely disconnected. Some smart TVs and smartphones, even when in off mode, maintain a WiFi connection. However, the extent of their WiFi usage can vary depending on the specific device and its settings.

Mobile Devices and WiFi Connections

Mobile devices like smartphones can be set to turn off their WiFi connections until they are in sleep mode. Nevertheless, many devices stay connected to WiFi networks. Turning off mobile data is a different matter; users can choose to use mobile data or not.

Getting Smart TVs to Automatically Connect to WiFi

To ensure your smart TV automatically connects to WiFi, follow these simple steps:

Press the HOME button on the remote. Go to the TV menu and choose Network Internet Easy Setup Wi-Fi. Select the appropriate WiFi network from the available options.

Follow the on-screen instructions to complete the setup.

Smart TVs When Turned Off

When a smart TV is powered off, the screen turns off, but the computer that drives it may still be active. Recent case studies have shown that even when a smart TV is perceived to be off, it can still engage in internet activity.

For instance, I observed my TCM/Roku smart TV attempting to connect to trackers within seconds of logging into the firewall's web UI, despite it being off. The only way to completely stop this activity is to disconnect the TV from the power source.

Power Off and WiFi Disconnection

Only when a smart TV is powered on, it can use WiFi. Whether it's in sleep mode or powered down entirely, the router won't detect the TV, meaning it doesn't use WiFi consistently. Similarly, if a smart TV is completely turned off, it will not use WiFi.

One user, for example, noted that their smart TV is connected to the network via Ethernet. Even 10 to 15 minutes after it has been turned off, it still maintains a live network connection due to the live network interface. After this period, it completely shuts off, and its network interface no longer draws power.

Some TVs have built-in features that allow them to be booted up using a wake-on-LAN (WoL) magic packet. While the TV is off and not using WiFi, the WiFi antenna and interface are powered enough to receive a WoL packet.

It's worth noting that different smart TVs might have different behaviors, and some may remain more active even when off.

Understanding these nuances can help users manage their smart TVs more effectively, both in terms of energy consumption and internet privacy.
